FAA Airline Transport Pilot (ATM)Human Factors and CRMMedium
A junior first officer notices the captain is configuring the aircraft for an approach that appears unstable but hesitates to speak up due to the captain's seniority and experience. This scenario best illustrates a breakdown related to:
- AWorkload management
- BConfirmation bias
- CAuthority gradient
- DVigilance decrement
Show answer & explanationAnswer & explanation
Correct answer: C. Authority gradient
Authority gradient refers to the perceived difference in rank, experience, or authority between crewmembers that can inhibit a junior crewmember from voicing concerns or challenging a senior pilot's decisions, a key CRM concept tied to communication and assertiveness training.
Why the other options are wrong
- A. Workload management refers to distributing and prioritizing tasks, not hesitancy to speak up due to rank.
- B. Confirmation bias is seeking information that confirms existing beliefs, not a rank-based communication barrier.
- D. Vigilance decrement refers to declining attention over time during monotonous tasks, not interpersonal hesitancy.
Authority Gradient
The perceived power distance between crewmembers of different rank or experience that can affect communication and assertiveness in the cockpit.
- A steep gradient can silence junior crew from raising safety concerns
- A too-flat gradient can undermine command authority and discipline
- CRM training promotes assertive communication regardless of rank
- Techniques like the 'two-challenge rule' help flatten dangerous gradients
Memory trick: Steep gradient = silent first officer; CRM flattens the slope for open communication
